A1] plication filed m 27,

To all whom it may (on-Gem: Be it known that I, Tiroiims E. Cox, a citizen of the United States of America, residing at Birmingham, in the county of Jefferson and State of Alabama, have invented certainnew and useful -lhnprovements in Wrench Attachments, of which the following is a specification. I

My invention relates to an attachment for socket wrenches adaptedv to enable an operator with the same tool to hold the nut or bolt head on one side of the work and toturn the bolt head or nut on the other side of the work to thereby quickly apply or remove nuts and bolts. Y

In the present practice it is necessary to apply a wrench or similar device to the bolt head or nut on one side of the work and to hold it while turning by another wrench the nut or bolt on the opposite side of the work, and as a general rule for speedy work it requires one operator for each wrench.

The purpose of my invention is to equip a wrench with an attachment adapted to engage the nut or bolt on the opposite side of the work from the wrench that is being operated and to hold it during the screwing and unscrewing operation.

It is a feature of my invention that this attachment shall be adapted for ready at tachment to and detachment from any standard type of wrench having an end socket. The attachment can obviously be modified to suit different classes of work.

My invention in its preferred embodiment" only will be best understood by reference to the accompanying drawings, in which z- Fig. 1 is a plan view of the wrench with my attachment showing the same about to be applied to the work.

Fig. 2 is a side elevation. of Fig. 1, the dotted lines showing the-manner of attachment of the wrench to the nut grip.

Fig. 3 is a detail perspective view of the nut grip with which the wrench is adapted to detachably connect.

Similar reference numerals refer to like parts throughout the drawings.

I have illustrated my invention in combination with a wrench comprising a brace handle or shank 1 and an end wrench socket 2. The wrench shank adjacent to the socket is cylindrical and adapted, when disposed crosswise, to be inserted between the rewnnnorr nTTAoHJnnnT.

between the overhanging lips of the hooks and the frame to permit the shank of the wrench to be swung into alignment with the body and to beengaged by both hooks which leave it free for rotation and longitudinal play inthe frame. In the'bight of the bent metal frame 5 I insert and secure bythe rivet 6 the shank 'Z of the nut grip attachnient. This'attachment comprises a nut receiving socket 8 connected, to; the right angledbend at the end of the shank and disposed in alignment wit-h the shank of the wrench 1 when in operating position. An ejector plunger 9 is mounted in the socket 8 free for a longitudinal play limited by its head in the socket and its enlarged. outer end, the enlargement at both ends of the ejector preventing its disengagement from the socket 8. i i

As illustrated in Fig. 1, I show a screw bolt 10 having a castellated nut 11 mounted.

on its end and disposed on the opposite side of the work 12 from the head of the bolt. In the position of the parts shown in this Fig. 1. the wrench is supposed to be working in vertical position and the nut grip will therefore be free to drop by gravity so that its socket 8 will receive and hold the nut 11.

In doing this the frame 5 is free to slip down 5 with the wrench and thus the wrench with in which willenable the nut grip to be applied to the wvorlr. The wrench can be I claim as new and desire to secure by Letters Patent is:

1. T he combination with a socket wrench having a shank portion in alignment with the-axis'of the wrench socket, of a nut grip socket closed at its outer end and having its inner open end disposed in spaced opposition to the wrench socket, means to slidably connect the grip to the wrench shank, leaving the latter free to rotate about its axis, and an ejector plunger mounted in the grip socket and having, a, shank projecting through its closed outer end.

2. An attachment for a socket wrench having a wrench shank, comprising a frame having a pair of oppositely disposed overhanging closely associated jaws spaced for the reception between them of a transversely disposed wrench shank, the overhung ends of the jaws being spaced from the frame sufliciently to permit the wrench shank to be slidably engaged under both jaws when swung into alignment therewith, and a nut gri mounted onthe frame and having a soc et inturned towards and aligning with the jaws.

- 3. The combination with a socket wrench having a cylindrical shank aligning with its socket, of an attachment having a holder socket closed at one end and adapted to align with and face with its open end. towards the wrench socket, and a pair of rigidly connected reversely disposed angled elements adapted to slidably connect said attachment socket to the wrench shank, leaving the latter free to turn and move axially relatively to such element;
